CARDING AND SPINNING MACHINERY: FOR THE MANUFACTURE OFASBESTUS YARN, &c. i

SPECIFICATION formingpart of Letters Patent No. 293,391, dated February 12, 1884.

Application filed Mareh 16,1882. (X model.) i

To all whom, it many concern:

Be it known that I, \VILLIAM WVOOD, a citizen of the United States, residing at Philadel- .phia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements inCarding and Spinmake and use the same, reference being had to the accompanying drawings, and to letters or figures of refercnce markedthereon, which U form a part of this specification.

My invention relates to carding andspinning doffers D D, sectional dofting-combs I 1, auto- 1 machinery for the manufacture ofasbestus yarn,

site direction to that in'Fig.:3.

&c. 5 and it consists in the combination of doffers divided into three or moresectionsaccording to the width of the carding-machine used and the size of the thread desired,withf separate sectional dotting-combs, adj ustablerei ceiving-shells, automatic twisting-tubes, and delivering-rollers to each section, all being on one machine. I attain theseobjects by thef combination of the several devices shown in{ the accompanying drawings, in which- V g Figure 1 is a perspective View of a carding-5 engine with my improvement applied thereto. Fig. 2 is an elevation of adjustable receiving-I shell and automatic adjusting twisting-tube, I

with, supports or standards therefor. Fig.

on line 3 3 Fig. 6. i i y My improvement is specially adapted to carding and spinning or twisting asbestus, amianthus, and chr'ysotile, (which are allknown commercially by the name of asbestus.) Owingto their smooth and slippery nature, it has heretofore been difficult to spin or handle them without apreliminary or false twist or the admixture of other fiber. By the use of my improvement the asbestus thread is spun by it without any preliminary or false twist,

or the admixtureot other fibers, or subsequent twisting or spinning, and can be woven into cloth or used as wick-or packing, according to the twist required and givento it.

I am aware that asbestus has been twisted or spun into thread by hand and bypower machinery by the admixture of vegetable or other fibers, in order to keep the asbestus together and enable it to be workedon the machine, as, owing to the smooth and slippery nature of the asbestus fiber, it is very difficult to handle it without such addition and without a positive twist, such as I put in by my device.

In carrying out my invention the sectional ,matio adjusting twisting-tubes J J, delivering-rollers K K, andspools M. M, in combination with the receiving-shells H H, are driven by, pulleys, belting, and gearing suitably arranged for the purpose, as follows: the doffer-shaftsQ Qbeing driven, as usual, from the end of the main cylinder X by a belt, Z,

running from a pulley on the end of the cylinder-shaft to'a pulley, a, geared to the dot"- fer-shaft wheels I) b by, means of apinion secured to a studin said pulley. j The sectional doffing'combs I I are arrangedon two shafts in front of and corresponding in number with the sectional doffers D D. The comb-shaftswhich are of the form shown, for instance, in

,the patent to E. \VrighaNo. 188,833-have the ordinary vibratory motion usual insuchcombshafts, and are driven, as usual, by belts from the ends of the fancy shaft 0 c, the doffing combs or knives being divided into sections, to

admit the twisting-tubes J J and delivering- -rollers K K into their proper positions, as shown. The automatic adjusting, twistingtubes J J are driven by belting O 0' from a counter-shaft, V, in front of the machine, this 'counter-shai'tV being driven by a belt, (1 d,

from the carrying-shaft under the cardingengine, this carrying-shaft '6 being the, same shaft that carries the stripper and fancy belt, asusual. The delivering-rollers K K are driven by;bevel-gearingv]? I on the doffershafts QQ at the end of each sectional doffer -D D. The top bobbinrwin'ding roller, U, is

driven bya belt, f, from a pulley, w, .on the top doffer shafu Q, the bottombobbin-wind ing roller, U, being driven by a belt, 9, running from a pulley on the top roller, U, to a pulley, c, on said bottom roller, the bobbins M M being revolved by friction as they rest on the top of the rollers U U, the top windthread required. The spacetat the end of and between the sectional doffers "D Dnand corresponding sectional dotting-combs I I gives the necessary room for the automatic adjusting twisting-tubes J J and delivering-rollersK Kf and the gearing driving the rollers, which' gearin g may be of the usual kind and character used in machinery, and suitably arranged for the purpose, as shown in the drawings. Iarran-ge the sectional doffers D D on two' or more shafts, Q and Q, one shaft, Q, above the other shaft, Q, the sectional doffers D D on the uppershaft, Q, being over the twisting-tubes J and delivering-rollers K ofthelower series of sectional doffers D, so that the stufimaybc taken off the whole length of the cylinder);

by the sectional doffers D and 'D WlbhOlllllD terfering with each other. I

As a matter of"convenience,- a1 1d for the purpose of changing theposition of the receiv ing-shells H H, Imake them adjustable to suit the quantity and quality of the material used, the adjustment being-effected byraisirng or lowering either end of: the receiving-shell H H, or the whole shell, bymeans of the-adjusting-screw h 'and'slotted standard z. The

"object and purpose of placing'the adjustable receiving-shells in the slightly-inclined position or angle shown in-the drawings, Figs. 2, 5, and 6, is to enable thein'to be adjusted'to. allow sufficient space below the dofter-comb at the end farthest from. its twisting-tube for the accumulation of the loose material as it is combed therein, where it is very loose and occupies much space and becomes smaller, occupying less space below the dotting-comb as it is gradually twisted and drawn nearer to and into the twisting-tube. Any difference in the quality andlength of the fiber used will require a change in the. angle 'at which the reeeivingshell must be set to, give the best results. As long fiber will take the twist bet ter than short fiber, the-latter must be held more closely to the doffing 'comb or knife -'at the end farthest from the twisting-tube and requires the shell to beraised proportionally at that end. The size of thread is governed rollers K K.

twisting tube or head may be used; but I preare composed of a conical tube, with shoulders 7a 7a and pulleyZ near the larger end, the point m being beveled off on one side of the apex, and fitted with an elastic plate, N N, notched at'the apex 0, and attached at the base 19 to the cone of the twisting-tube J. The shoulders of my twisting-tube J J are supported by a standard, q, with two bearings, 1' 1", the caps or covers 8 s of the bearings being hinged on and fastened or released by the movable key t t, so that the twisting-tube J J may revolve freely in its bearings r 1" when driven by the belt 0 0 from the counter-shaft V. The notched elastic plate N N is adjusted so that it will press the stuff which is being twisted against the opposite side of the apex of the cone m, and at the same time have sufficient elasticity to allow the twisted stuff or thread L L to be drawn through it by the delivering- Any other suitable form of ferthe one described.

The operation'of my improvement is as follows: The fiber used, (asbestus, amianthus, or ch'rysotile,) in proper condition, isfed to the carding-engine at w in the usual manner, and carried around the cylinder X and cards 1: o 'v o, as usual, to the sectional doffers D D, from which it is combed by the combs I I onto the receiving-shells H H, which support it while it is being twisted or spun by the automatic adjustingtWisting-tubes J J and delivering-rollers K K,which draw it through the twistingtube J J and deliver it to the bobbins M M, which rest on the winding-rollers U U, and are driven by them by friction, all being driven by suitable pulleys, belting, and gearing, as

previously described. As inthe accompanying drawings, if a carding-engine, Fig. l, of

twenty-four (24) inches in width, with six (6) sectional doffers (three on each shaft) of four (4) inches each,to make acertain size of thread, be employed, as the size of the carding-engine is increased, the number of sectional doffe'rs may be increased or the size of the thread varied. As the number of sectional doffers is increased, additional combs, adjustable receiving-shells, automatic adjusting twistingtubes, delivering-rollers, and bobbins must be added in proportion.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination,with the main cylinder, of the sectional doffer-cylinders, the doffingcombs, receiving-shells, twisting-tubes, delivery-rollers, bobbin-winding rollers, and means for operating said parts, substantially as described. v 2.
